Details

This monument includes a vermin trap situated near the summit of Great
Trowlesworthy Tor overlooking the valley of the Blacka Brook. The vermin trap
includes two lengths of drystone wall forming a `V'-shaped trap pointing
towards a rock face from which it is separated by a 0.8m wide gap. The
position of the trap suggests that the rock face was intended to help
encourage the vermin into the trapping area, which was originally sited at the
point where the two lengths of walling meet. The rubble walls average 1.3m
wide and 0.5m high, whilst the northern arm is 10.5m long and the southern arm
is 11m long.
Vermin approaching their quarry tend to seek a route that provides visual
cover and the purpose of a trap was to funnel predators along ditches or
beside walls to a central point where they could be trapped.
This vermin trap forms part of Trowlesworthy Warren, which includes around
64 pillow mounds and 40 vermin traps scattered along the slopes of Little and
Great Trowlesworthy Tors. The boundaries of the warren are denoted by the
River Plym, Spanish Lake and Blacka Brook. Trowlesworthy Warren is generally
accepted as the oldest surviving warren on the Moor. Sometime before 1292
Samson de Traylesworthie was granted land for rabbit farming by Baldwin de
Redvers, Earl of Devon. Many years later in 1551, the warren was leased to
William Woollcombe. The warren appears to have remained in constant use until
the first half of the 20th century.
This monument is in the care of the Secretary of State.

Reasons for Scheduling

Dartmoor is the largest expanse of open moorland in southern Britain and,
because of exceptional conditions of preservation, it is also one of the most
complete examples of upland relict landscape in the whole country. The great
wealth and diversity of archaeological remains provide direct evidence for
human exploitation of the Moor from the early prehistoric period onwards. The
well-preserved and often visible relationship between settlement sites, major
land boundaries, trackways, ceremonial and funerary monuments as well as later
industrial remains, gives significant insights into successive changes in the
pattern of land-use through time.
Warrens are areas of land set aside for the breeding and management of rabbits
or hares. They usually include a series of purpose-built breeding places,
known as pillow mounds and buries, vermin traps and enclosures designed to
contain and protect the animals, and living quarters for the warrener who kept
charge of the warren.
Pillow mounds are low oblong-shaped mounds of soil and/or stones in which the
animals lived. They are usually between 15m and 40m long and between 5m and
10m wide. Most have a ditch around at least three sides to facilitate
drainage. Inside are a series of narrow interconnecting trenches. These were
excavated and covered with stone or turf before the mound was constructed.
Vermin traps of various kinds are found within most warrens. These include a
small stone-lined passage into which the predator was funnelled by a series of
ditches or walls. Over 100 vermin traps have been recorded on the Moor, with
the majority lying in the Plym Valley.
Warren boundaries were often defined by a combination of natural features such
as rivers. Within the warrens themselves smaller enclosed areas defined by a
ditch and bank are sometimes found, and some of these may have been
specialised breeding areas. Many of the warrens on the Moor contain a house in
which the warrener lived.
Most of the surviving warren earthworks probably date to between the 17th
century and the later 19th century, with some continuing in use into the early
20th century. At least 22 warrens are known to exist on the Moor and together
they contribute to our understanding of the medieval and post-medieval
exploitation of the area. All well-preserved warrens are considered worthy of
protection.

The vermin trap 90m west of Great Trowlesworthy Tor survives well, forms part
of the nationally important Trowlesworthy Warren and contains information
relating to the exploitation of rabbits in the Upper Plym valley. This valley
contains the densest concentration of vermin traps and other structures
associated with rabbit farming on the Moor.
